DIY Survival Water Purification Systems
When you are in a survival situation, clean drinking water is very important. Anyone can stay alive without food, but without sanitary water, you won't last longer than a couple days. Realistically, you should be able to collect rain water or have some way of boiling to purify it. This is not always possible when you are in a survival situation, which means you will have to create a water purification system yourself.
- Create a container to keep your water in. Using a piece of bark to form a cone with a vine to secure it or a piece of cloth and string or cord will make a good filter.
- Tie the bottom of the container shut so that you can add the contents of the filter. The water should still be able to seep through the bottom of the filter and into the collection container.
- Tie a cord around the top of the container and hang it from a tree approximately chest high. You want to keep it off the ground so that the water can filter through instead of sitting there.
- Add a layer of rocks to the bottom of the container to use as a filtration system. If you can find some sand, place some on top of the rocks to use as an extra filter. Use at least two layers each of rocks and sand so that the water will filter through and become as clean as possible.
- Pour the dirty or murky water into the top of the make-shift purification system. It will slowly begin to filter through the rocks and sand into the collection container. It may take a few hours for all the water to purify. You may need to pass the water through the purification system more than once.
- Boil the purified water once it has gone through at least once. This will ensure that any germs remaining are killed.
